Three humble ingredients – potato, cabbage and bacon – that’s all it takes to cook trinxat, the quintessential Catalan wintertime comfort dish. Potatoes and cabbage are boiled and mixed with fried bacon, and everything is cooked as a mash in a pan until it resembles a potato omelet. Its simple ingredients and even simpler preparation are exactly what make this dish so delicious.

After four generations of doing business in the same shop – housed since 1907 in a beautiful moderniste building between Paseo de Gràcia and Gran de Gràcia – the beloved patisserie La Colmena has closed. One of Barcelona’s most iconic and historic establishments, La Colmena made some of the best artisanal candies, turrón de Jijona, Lenten fritters and Swiss rolls (called a brazo de gitano, or “Gypsy arm” in Spanish) in the neighborhood, and was run by siblings Cristina and Francesc Font, the fifth generation of the family. The venue was effectively forced to close because its rent was set to more than triple, and because of a requirement by City Hall that they restore and update the premises. Although Barcelona residents were aware of the situation, the owners’ decision to close still came as something of a shock to longtime customers.

For more than a year, we’ve been trying to find a way to approach the mammoth subject of Spanish wine with a suitable culinary activity. Barcelona has a sophisticated wine scene representing the best of Catalonia and all of Spain. In sober rooms, we attended tastings that were a bit too academic for our taste. We visited new-age wine bars with a list limited to Catalan bio/organic wines and nothing else. In Barcelona’s many wine shops, we sampled when we could and shopped for bottles, as we might in any international city. During this research, we got up close and personal with what was in the glass but often felt disconnected from the local culture of drinking wine.

Barcelona is paradise for those with a sweet tooth. Pastries, nougats, cakes, chocolates and candies can be found in every neighborhood, all year long. We’ve written previously about turrón, artisanal gelats, chocolate and seasonal specialties such as panellets, tortells and buñuelos, but beyond of all these (and others), there are the city’s beloved hard candies. Let’s start with the eminence grise. The patisserie La Colmena (“The Hive”) has two locations, the first of which opened in 1835 on Gran de Gràcia, the second in 1849 on Plaça de Àngel. For a time, the shops were run by different branches of the same family, and eventually each went its separate way. Both shops continue to make Spain’s oldest artisanal candies, square-shaped sweets flavored with honey or Mediterranean flavors like thyme, rosemary and citrus. The original candy was made with single-varietal honey from rosemary flowers and sugar and was hugely popular in both shops’ neighborhoods. As might be expected, the two businesses share more than just genetics: All the candies in both shops are made by hand, with natural essences and without any kind of artificial flavors or preservatives. There are a few differences between the two Colmenas too.

Up in the high streets of the Horta-Guinardó hills, not far from the old historic building of L’Hospital de La Santa Creu i Sant Pau, there is a restaurant with a big concentration of culinary talent but just eight tables. To make things worse, they are only available during two hours for lunch. Fortunately for those who can’t snag one of those precious tables, La Cuina del Guinardó (“Guinardo’s Kitchen”), a Catalan traditional market-cuisine restaurant, is also a store selling cooked food to take away from morning to evening and a great wine shop, with a tasting area in the upper level.

The rustic family favorite Can Pineda has been holding down this corner of Barcelona’s El Clot neighborhood since 1904. It was not a restaurant originally, but a typical wine shop and canteen, where plenty of life could be found amongst the wooden barrels that now slumber peacefully on their perch up above the dining room. At that time, the place was frequented by local factory workers, who would come for a glass of wine to go with a simple meal or to drink while warming up their lunch boxes. The then-owners would put a pine branch on the door to signal the arrival of the vi novell, or new wine of the year, and from the pine, pi in Catalan, came the name Can Pineda, which translates roughly to “The Pine House.” Today, El Clot is part of the new high-tech 22@ district, which is focused on innovation and research but maintains in its oldest streets the spirit of the village (Sant Martí de Provençals) that once flourished here, with its own market (dating back to 1889) and walls that remain from Barcelona’s first Industrial Age. Can Pineda sits right in the middle, a small but welcoming eatery with just 30 seats, decorated with the characteristic blue azulejos tiles, those wooden barrels and a few excellent hams hanging behind the bar.

Editor’s note: We’re celebrating another year of excellent backstreets eating by taking a look back at our favorite restaurants and dishes of 2015. La Panxa del Bisbe Xavi Codina has created a menu of almost 30 tapas or platillos (small dishes) and four desserts, combining traditional Catalan cuisine with international influences that Codina has encountered in his life or in the neighborhood. Much of the menu changes according to season and customers’ tastes, but there are a few perennial favorites, such as the homey croquettes, with their generous quantity of chicken and carrots; duck liver with pears and wine; and the cap i pota, a traditional dish made from pork trotters and head, which the chef tweaks throughout the year.

2015 has been a banner year for the herb-infused liqueur known as ratafia. In the little town of Santa Coloma de Farners, within the Catalan province of Girona, locals have been making this unique libation for centuries, with each family passing down their own version of the drink from one generation to the next. In 1997, within the county’s official records, came a major food discovery – written recipes for three distinct styles of ratafia dating back to 1842, which are now recognized as the oldest of their kind in Catalonia. These handwritten lists of ingredients (along with other culinary notations, savory recipes and home remedies) were discovered in the old notebooks of Francesc Rosquellas, once the proprietor of a café/restaurant in Santa Coloma de Farners whose name had long since been forgotten.

Manolo, the protagonist of Juan Marsé’s 1965 novel, Last Evenings with Teresa, possibly the saddest Spanish love novel ever written, spends a great deal of his time drinking and playing cards with the local elders in Las Delicias. Well known to locals and Marsé’s devotees but unknown to many Barcelonans, this bar was founded in the Carmel neighborhood in the mid-1920s using a natural cave that was turned into a bomb shelter built just below the republican air defenses during the Spanish Civil War (1936-1939). El Carmel, a working-class neighborhood on Rovira hill with spectacular views over the city, was home to the Andalusian, Galician, Aragonese, Castilian and Extremaduran immigrants who moved to Barcelona looking for brighter futures during the postwar years, the 1960s and ’70s. Las Delicias soon became their favorite local eatery, as portions were larger than usual. Decades later, portions are still very generous, the bar is still a neighborhood institution and the menu still reflects the origins of those who once settled down here. There are Andalucian specialties such as calamares a la andaluza (deep-fried squid, €6.50), morcilla de Jaén (pork blood sausage, €1.60) and pincho moruno (marinated chicken on a skewer, €4.50); Galician specialties like pimientos de Padrón (€5.25), lacón con cachelos (boiled pork shank, €7) and pulpo a la gallega (boiled octopus, €13.95); Aragonese longaniza (pork sausage, €5.25) and Castilian callos (beef tripe stew, €5.25).

When you live in a medieval town that is as beautifully preserved as the little Catalonian hamlet of Peratallada, you are never too old for dress-up. All year round, these worn stone walls and charming plaças effortlessly take visitors back in time to the 10th century. However, on the first weekend of October, the sights, sounds, smells and tastes of the Middle Ages return to the narrow streets of this historic bastion in full and festive glory.

El Resolís has already been through several reincarnations, each time as a meeting place for strong, yet completely different – sometimes opposing – social groups. But even across time, changing styles and menu updates and under different owners and chefs, the place has never altered its name or its basic culinary M.O.: traditional, populist, affordable. Located in the heart of the gypsy Gràcia district, El Resolís was founded in the late 19th century. During the second half of the 20th century, it became the headquarters and the social meeting point for the Falange, the fascist and sole legal party of the Francoist dictatorship. This extremely conservative regime repressed the official use of Catalan and other cultural expressions in Catalonia and other Spanish regions.

With all the talk about the benefits of quinoa, chia seeds, goji berries and similar superfoods, we can’t help but be a little taken aback when Dolors, one of the owners of the restaurant Can Vilaró, explains the benefits of eating cap i pota, a traditional Catalan stew made with calf’s head and leg and chickpeas. According to her, the gelatinous chunks of meat make the skin glow and fight wrinkles. “It works as well as the most expensive collagen facial cream available at stores,” she says with a cheeky smile.

“In Cadaqués, we cure anchovies differently than anywhere else,” Rafel Martín Faixó told us. We were sitting at long wooden tables outside of his family’s winery, on a sunbaked hilltop in Cadaqués, two and a half hours north of Barcelona. Rafel is the son of Carmen Faixó and Rafa Martín Mota, and together with his sisters Ester and Georgina, the five of them comprise the Martín Faixó (MF family) brand, featuring three restaurants in Cadaqués and the Celler Martín Faixó winery, with a rural tourism guesthouse on-site.

Editor's note: To inaugurate our new series, Building Blocks, which explores the fundamental ingredients of the cuisines we cover, we turn to Spain, where anchovies play a large role in the cooking of many regions there. Anchoa, boquerón and bocarte: These names – in Spanish, Basque and Catalan, respectively – all describe the same little fish, the anchovy, and to make matters more confusing, the names also indicate how the fish is prepared, depending on what region you’re in.

Kim Díaz, a well-known local restaurateur and owner of Bar Mut tapas bar and El Mutis cocktail bar, wanted to pay tribute to one of the most humble and sadly underrated Spanish snacks, the sandwich. Sandwiches are generally made by most Barcelonan bars with defrosted cheap bread and greasy fillings, and good ones are not easy to find in the city (though we have written about some great ones). Entrepanes Díaz opened last February with the goal of giving the sandwich the respect it deserves.
